IMPROVEMENT IN SEWING-MACHINE NEEDLES.

Specification forming part of Letters Patent No. 188,648, dated March20, 1877; application filed August 26, 1876.

To all whom it may concern:

Be it known that I, LOUIS LOESKE, of New York, in the county of New Yorkand State of New York, have invented a new and valuable Improvement inSewing-Machine 'Needles; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part ofthis specification, and to the letters and figures of reference markedthereon.

Figure l of the drawings is a representation of a side view, showing myneedle attached to a machine, and Fig. 2 is a side view of the needle.

This invention relates to sewing-machine needles; and it consists incombining together two needles, which are arranged side by side, thehead of one of the needles being united to the shank of the other, andone of the needle-shanks projecting above the other, and adapted to bereceived in the socket in the needle-bar, whereby said double needle canbe employed in the ordinary needle-bar of a sewing-machine, having asingle socket for the reception of the needle, as will be hereinaftermore fully set forth.

In the accompanying drawing, A designates a shank, to which are rigidlyattached a short needle, B, and a longer needle, B, both of said needlesbeing constructed, as

usual, with a slight curvature, and pointed and perforated in the usualmanner. The shorter needle, B, is an extension of shank A in the directlongitudinal line thereof, and the longer needle, B, is parallel to saidshorter 'needle B. The arrangement of said needles may, however, bemodified without departing from the spirit and scope of my invention.Thus neither of said needles may be an exact continuation of said shank,in the longitudinal line thereof, or the longer one may be such acontinuation and the shorter one may be parallel thereto, and on oneside of said longitudinal line. 0 designates the needlebar, providedwith a socket, c, in which shank A is secured.

The object of the construction described is as follows: For sewingbutton-holes and for some other purposes two needles are ordinarilyattached to the same needle-bar, and operated simultaneously. As saidneedle-bars are usually constructed with only one needlesecuring hole orsocket, it then becomes necessary to drill an additional hole in saidneedle-bar to receive the additional needle. This involves aconsiderable waste of time and labor, beside some expense. I obviatethis loss and annoyance by constructing my needles so that, while theyanswer the purposes of two separate needles in every respect, theyrequire but one hole or socket in the needlebar of the sewing-machinefor their attachment. Shank A is inserted in said hole and theresecured. The two needles B B are then operated simultaneously by saidneedle-bar and shank, and the sewing is accomplished.

The invention above .described is applicable to embroidering, and tovarious other purposes, as well as to sewing button-holes. The needlesmay be straight instead of curved, so as to be adapted for use onstraight-needle machines.

What I claim as new, and desire to secure by Letters Patent, is

The double needle B B herein described, the head of the needle B beingunited rigidly to the shank of the needle B, and the latter projectingabove the needle B, whereby the double needle is adapted to be appliedto the needle-bar of a sewing-machine having but one needle-socket,substantially as described.

In testimony that 1 claim the above I have hereunto subscribed my namein the presence of two Witnesses.
